Modes of variation identified in the glucosinolate data

#	Variation among plants	Chemical background	Time-points
1	Increased concentrations in SJA and to a lesser extent in RJA plants	Positive correlation among NEO and GBC	1-14
2	A. Contrast compensating for relative differences in glucosinolate levels between day 1 and the other days	Negative correlation among NEO and GBC	1 (SJA) 1-14 (RJA)
	B. Increased variation among SJA plants compared to CON and RJA plants		7-14
3	Increased concentrations in RJA plants compared to CON plants	Positive correlations among PRO, GBN and GNA	7-14
4	Increased variation among RJA plants		1
